Patio block paving sub-base

Antscran · 13 May 2023

Hi All,

Have just cleared an area for block paving and need to dig a bit more, what is the recommended sub-base depth for block paving used as a patio only?

I have a membrane to lay down first then I thinking 100mm Scalps (have received a reasonable offer for 40mm Limestone Scalps) or is more needed?

The 30mm of sand and then the 50mm blocks on top.

Thanks,
Ant
